I applied through an employee referral. I interviewed at Amazon in Jan 2020
Interview
The interview was composed of two rounds: 1) research phone call and 2) coding phone call.
Research phone call was with the manager and we hit off pretty well with the interview, and the manager wanted to offer me the internship position.
I didn't prepare much for the coding interview, as I was expecting a research role. This led to the second interviewer to decline me. Make sure to prep for both aspect of the job!

Applied for Amazon AGI. After first round, it will go into full round of multiple interviews. Lots of modern LLM training technic questions. There are still some behavioral questions, but less than general Amazon roles.
Interviewed with 1 phone screen, 1 coding, 2 ml design and 2 lp rounds. Most questions were non-leetcode questions more related to day to day ml implementations. The questions were very practical.
